HollywoodLife.com spoke to a source about Vanessa’s relationship with Austin Butler and they gave us the scoop on how things are going. Plus, one of Zac’s friends reveals his thoughts on his ex and her new man!

“It isn’t a serious thing at all,” reveals an insider in Vanessa’s camp. “She’s having fun hooking up with him but no official relationship has flourished yet. They’d hooked up before their Saturday night out. It’s a friends with benefits situation.”

Eyewitnesses at Bob’s Big Boy restaurant in Burbank said Vanessa and Austin were there in a group. “She looked way more interested in him than he was in her, but they both looked like an item,” says a source who was there on Saturday. “Her friends acted like it was completely normal for them to be so coupled up.”

But as soon as the two went outside where the paparazzi were waiting, they “completely stopped acting like a couple and avoided interaction in front of the cameras” another eyewitness notes.

So what does Vanessa’s famous ex Zac Efron have to say about all of this? A friend of Zac’s confesses, “He doesn’t care about her new relationships as long as she is happy.”
